Coming on the scene with a throwback style that betrayed his years, Pittsburgh-based rapper Mac Miller had just turned 18 when he spent 2010 making his name through mixtapes and video-sharing websites. Born Malcolm McCormick, Miller first used the alias "Easy Mac," a name referenced on his debut mixtape, 2007's But My Mackin' Ain't Easy. His K.I.D.S. mixtape became his breakthrough when it was released in August of 2010, earning plenty of attention from hip-hop blogs and landing Miller a recording contract with Rostrum Records.
